WINDING MECHANISM Filed April 12, 1950 ATTORN EY UNITEDl sra GUsTAvEfP.BAER, or FAIRFIELD, coNNEC'rIoUr, AssIGNOR To COLUMBIAY PIiovNo- GRAPHCOMPANY, INC., or BRIDGEPOR'I, COlvivnCrICrr'r, A CORPORATION `oro'cfr'zr-Y i WINDING MnCHANIsM IThis invention relates to phonographs orf talking machines and has particular rela' tion'to the means forwinding-thespring motors of such machines. 1 i

In certain types of these machines particularly in those known asportablesitis desirable that while the cabinet Or-boX be wellproportioned themachine asa whole be comparatively light in weight. Tokeep the cabinet as small as possible and yet of pleasf lng proportionsit is necessary that it should be of small height. v Y Heretofore, whenit was necessary to wind the `motor of a portable where the cabinet wasof small height andthe Winding lcrank a partition Vwith the windingcrank also above the motorboard and the'parts are` so arranged and.constructed that the winding Crank Vmay be readily moved to windingposi- V2 the winding mechanism for the'motor 11- tion or to a storedposition within the cabinet without disconnecting the winding crank andstoring it as aloose part. A

A further object is to provide a portable phonograph including a novelVwinding mechanism in combination withV a horn, thefwindf ingvmechanismbeing so arranged that a horn of exceptional length may vbe used withoutcrimping, cutting or perforating it to provide' space for the vwindingcrank.

f Other objects and advantages will become l apparent `:trom` thefollowing detailed description taken in connection with the accompanyingdrawing wherein the invention 1s shown in two `'orrns. It is to beunderstood that this description and theaccompanying drawing are `forthe purpose of disclosing satisfactory embodiments of the inventioni930. serial No. 443,692.

construction, combination andA arrangement ofparts shown as changes maybe made and will. readily suggestI themselves to those skilled in theart. 'Therefora reference must be had to the claimsfora definition ofthe limitaionszof the invention.V

In the drawing: l'

- F'gurel is top plan view .of phonograph, the top being omitted and theturntable being shown i-n dotted lines and showing the application ofthe invention.

Fig: 2 is `a sectional view on the line 2 2.

Vof'Fig. 1-;vand y `Fig. 3 is a similarview showing a slightly dierentarrangement. f

Referring in detail to the drawing at 5 is Vshown the casing or mainportion of a porta-` ble phonograph `cabinet the to'p being omitted.Casing includesiront and rear walls 6 .and 7 and side walls 8 and 9.VWithin 'thetcasing and below the4 upper edgesV ofthe lwalls thereof isa partition or motor board l0."

` motor 11 is supported by the motor boardand includes` a frame12",'1nounti'ng` a spring barrel 13 to which is ASecured a rela= mediategear 15 drives a smally gear or pinion 16 secured to the usual uprightturntable kspindle or shaft 17 at its upper end carrying andserving torotate the turntable 18;

Referring'more particularly to Figs. land is shown as disposedabove'themotorboard 10. To :this end'the motor board is cutaway as at19'andbearings 21, 22, and 23 on the upper side of the motor `frame 12 projectthrough the opening inthe motorfboard'and are disposed above the motorboard. i `Also the spring barrelis mounted -upon a shaft 24: likewiseproj ecti'ng above the motor frame 12and the moto?V boardflO and at itsupper end carrying a worm gear 25. l

The winding Crank-26includes a handle 27 as is usual'and includes aportion 28 and mayfin'clude a threadable -connection as :at 29 or it maybe integral in the form Oflthe a portable Y vand that theinvention isnot limited tof the il Y tively large gear 14: which through an interyinvention'shown invFigs. 1 and 2.. This pori tion 28v isrotatablymounfed in the bearings and 22 passes through a worm 30 meshingwith the worm gear 25. Also between the bearings 2l and 22 andassociated with the worm v30 is a back winding preventoi 31 which asshown is in the form of a coil spring. y

It will be obvious that by turning the crank 26 t-he spring in springbarrel 13 will be Wound up since the shaft 24 will be rotated throughthe meshingA of worin 30 and worm' gear 25.

According to the invention as shown in Figs. l and 2 it is not necessaryto 'disconnect the winding crank 26 in order to dispose the saine withinthe casing 5 when the machine is not in use. To this end the portion 28of the winding crank is slidable through the worm 30 and connected indriving relation with the worm through a sleeve 32 slottedas at 33 `andwith which the portion 28 has driving relation through the medium of apin 34 carried by theportion 2,8 and disposed in the slot 33. Also, theside 9 Voi the casing is notched as at 35 and the winding crank 26operates in this notch. Y When it is desired to close the machine asfor` transportation, storage or the like it is but necessary to turn thecrank v26k untilits handle portion is disposedin a planefabove and inline with the remainder of the crank and then push inwardly on the crankthe lat- Y be turned down to lie against the motor board f l() in theposition in dotted lines in'Fig. l.

Of course, to again'extend the crank to oper-` ative position it is butnecessary to turn` it :to dispose tlie handle 27 above and in line Vwiththe major portion of the crank and to then pull outwardly on the same tohave the crank extend through the notch 35 as shown in Figs. l and 2. 1

Through the use of a motor and winding mechanism as described additionalspace within the casing 5 is made available forecciipancy by an enlargedhorn or amplifier of channel formation having its open side closed bythe partition or motor board. This isillustrated and as shownY theamplifier-36 extends from the base of a tone arm 37 shown inV dottedlines in Fig.A 1Y and carrying a reproducer 38 also shown in dottedlines.

' The base of the tonearm 37 is at onel rear corner of the motor board10 and the-amplifierV 36 extends along the side wall 9 of the casing,along the front wall'6 of the casing and is curved back along the sidewall 8 of the casing discharging through anopening 39 in the motor boardl0 at the back of the casing. Y i

Since thewinding crank is disposed above the kmotor board ..1(1.it doesYnot in any way interfere with the horn'36 and-it is not necessary tocrimp or perforate the horn to' make space for the winding crank.Further, owing to the fact that the winding mechanisni is disposed abovethe motor board, a cabinet of less depth may be used and space will beprovided in order that the `winding crank may be operated without theoccasion Vfor moving the casing 5 to the edge of the table or othersupport since the Winding crank will'be considerably elevated' above itsfrom the portion 28 keyed or otherwise secured to the worm 30. v

In this last form of the inventionvthe winding crank 26 would have to beunscrewedat 29 in order that it may be removed and disposed within thecasing when the macliineis closed as for storage, transportation or thelike'.

Having thusdescribed the invention what is claimed is: i l
